What are the wires under our seats?

I have a 04 wrx wagon that does not have heated seats. There are however wires that run from the center console to the seats, wraped in black plastic. Can't figure out what they are for since the seats aren't power seats.. Could it be that the car is wired for heated seats but just doesn't have the controls?

if there's a person in the seat, and i want to say some cars use the weight of the person in the seat for some calculation in the airbag deployment...maybe i'm dreaming/drinking...

Could be for sure airbag sensors. I had a 2006 toyota tacoma and if you set something heavy on the passenger seat a light on the dash would light up if you didn't buckle the seat belt. Nothing like that on the wrx, no way to turn off the airbag, etc. so my guess is that 04 was before such devices.

I just wonder if things like heated seats are actually installed on all seats, just not hooked up with the controler. Mass production seats and such it would seem easier to make them all the same and just not add the controller when it's assembled. Just a guess however.

Seems odd that both seats would have wiring, makes me wonder if they are for the heaters?

There will be a wire atached to your seatbelt that detects if your seatbelt is buckled and is connected in the SRS unit so if your not buckled in the airbags wont deploy kinda one of those thigs like "I wanna die.....im not going to wear my seat belt" then your cars senses that and says wish granted. And of course the airbag sensor the airbag sensor is yellow ALWAYS the other black one is the seat belt one idk if there are anyother ones those are the 2 that i have seen in every car ive worked on (of course I work at Honda) but i figure all cars are similar

The side impact Airbags are inside the seat, and I think that wire is for those. The seat belt sensor comes right out of the buckle as I recall. Those are the only wires attached to the seat in my 04 wagon (Switched them out for 04 STI seats and those were the only ones I had to deal with).
